Commemorate one of the darkest moments in Europe in recent history: In July 1995, Bosnian Serb militias invaded Srebrenica and killed around 8,000 Muslim men and boys within a few days. The massacre 25 years ago is considered the worst war crime in Europe since the end of the Second World War. To date, more than 80 mass graves have been discovered and around 7,000 victims have been identified. As part of the memorial event, the remains were buried by a few other identified people. On July 11, 1995, Srebrenica fell into Serbian hands. Women and children were separated from the men and taken to an area controlled by the Bosnian army. Around 40,000 Bosnian Muslims had previously been protected in the Srebrenica enclave under the protection of the United Nations. Former Bosnian Serb leader Radovan Karadžić and Bosnian-Serbian military chief Ratko Mladic were found guilty of genocide and sentenced to life imprisonment by the United Nations War Criminal Tribunal for Ex-Yugoslavia in The Hague for their responsibility for the massacre.
